One Basin, Full Depth, No Divider in the Way

A single-bowl sink gives you one uninterrupted basin for the jobs where a divider only gets in the way: washing a large roasting pan, filling a stockpot, or soaking a sheet tray flat. The 9-inch interior depth keeps water in the bowl and gives enough clearance for tall items. This is a workhorse configuration for a primary kitchen sink where volume and versatility matter more than a split workflow.

Quartz Composite in a True Matte Black

The Q-340 is made from quartz composite, which gives the sink a solid, stone-like density and a consistent color through the body. The Black finish is a true matte that pairs well with dark cabinetry, black or dark hardware, and both warm and cool countertop tones. A matte surface also handles daily contact better than a polished one visually, keeping water marks and minor wear from standing out over time.

Where This Sink Works Best

This sink belongs in a kitchen remodel or new build where the designer or homeowner is committing to a dark palette. Black undermount sinks have become a straightforward specification for kitchens built around matte black fixtures and pulls, dark shaker cabinetry, or a high-contrast look with white or light stone countertops. It also suits a professional or commercial-style kitchen where the sink is meant to recede visually and let the countertop material do the work. Because it is undermount only, it fits a laminate, solid surface, or granite counter being fabricated for the project, not a countertop swap into an existing cutout.
